I saw all of these at our Wal-Mart this weekend, just stocked with the regular comic packs. They seemed to have plenty of all three, at least at that time.
EDIT: Just thought I'd pass along a bit of info about the Lando/Stormie set, since a lot of people will likely pass on it. For some reason, I just felt like picking one up, and got a chance to open it last night and noticed that Lando's cape (which is red on the inside now) has the wire at the bottom similar to the O66 Jedi robes). Just thought I'd pass that along if anyone was interested.
